【 摘 要 】

Fluid structure interaction problems involving heat transfer are ubiquitous in engineering applications. Computational techniques are often required to obtain usable information about these problems. A Remeshed Vortex Method with immersed boundaries is presented capable of handling Fluid Structure Interaction problems along with moving boundaries. A novel solver is developed based on these principles in C++ to solve the Navier Stokes equations for incompressible flows. The Boussinesq approximation is used to model the thermal behaviour of the flow. This solver is then validated by solving for the flow past an isothermal heated cylinder. Different test cases where free, forced and mixed convection dominate are studied. The results obtained are compared to those in literature to validate the code. The ability of the code to capture moving boundaries is also verified. Following this, potential applications and scope for future work is identified.
